SCREEN AND BLIND FOR CAR-WINDOWS.

SPECIFICATION forming part of Letters Patent No. 253,241, dated February7, 1882. Application filed September 14, 1881. (No model.)

To all whom it may concern:

Be it known that 1, ISAAC M. VAN WAGNER, of Nyack, in the county ofRockland and State of New York, have invented certain new and usefulImprovements in Screens and Blinds for Gar-Windows, of which thefollowing is a specification.

The object of my invention is to provide for exclusion of smoke and dustfrom cars while the windows are open, and also to apply wire screens tocar-windows of ordinary construc tion without material changes.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

In the drawings, Figure l is a face view at the inside of the car of awindow provided with my blind and screen, the window-frame being insection. Fig. 2 is a vertical section on line :20 w of Fig. 1. Fig. 3 isa detail section, in larger size, on line 3 y of Fig. 1; and Fig. 4 is adetail section of one slat-pivot.

A is the window-frame, provided with sash B and blind G, sliding ingrooves, as usual, separated by the parting-strip a. Between the sashand the blind is the screen D, fitted in grooves formed in strip a, nextto the blind, such grooves being extended down to the sill of thewindow. The blind O is provided with slats c, hung by pivots d in theline of one edge, and connected by a bar, 0, in the line of the otheredge, for simultaneous operation of the slats. The slats are in tworows, separated by a center bar that is provided with a removableface-plate,f, which covers the slat-pivots. The face-plate is held byscrews to allow its removal for convenient insertion of new slats totake the place of broken ones. The pivots d are strengthened by a wire,g, passing into or wholly through from end to end of the slat, andbetween the contiguous pivots in the center bar there are spiral springsh,-for imparting friction to retain the slats in position as turned. Theside bars of the blind-frame are recessed at the lower end, as shown inFig. 1,

.so that the bottom of the blind may close down on the sill. This isessential in the combined blind and screen, and the recess avoids thenecessity of cutting the blind-groove out to the sill. The screen D isconnected to the blind O by a sliding spring-bolt, z, fitted in thelower bar of the blind-frame and entering a recess in the screen-frame.I prefer to fit the bolt 71 in connection with the raising-hook k ofcovering the screen. The blind-slats, being movable, can be set more orless open or entirely closed. Thevknob on the end of bolt i will beattached by a screw-thread, so that at any time it is desired to lockthe blind and screen together the knob can be removed and the lockingthus effected.

I am aware that a blind-frame has heretofore been adjustably secured ingrooves in a screenframe, and the latter also adjustably secured ingrooves in the window-opening, whereby the blind can be raised orlowered independently of the screen-frame, or both raisedsimultaneously; but the screen cannot be raised independentlyoftheblind, as in my invention; and I am also aware that swinging blindshinged to a window casing and covering the opening, which opening isalso .provided with screenfraines hinged to the window-casing, theblinds and screen frames being adapted to be connected with anddisconnected from each other,

whereby they'may be operated simultaneously with or independently ofeach other, have heretot'ore been employed, and I therefore lay no claimto such construction, my invention being,

confined to a blind and screen adapted both to slide simultaneously withor each independently of the other in a window-frame.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In a car-window, the combination ofa blindand a screen fitted to slide in grooves in a win- 3.
